To all 'whom t may camera.'

Be it known that li, Lorenzo Fnnnnnr, 'a citizen of the United States, residin at akIand, county of Alameda, State of alifornia, have invented certain new and useful ing l have shownan aeroplane containing.

my invention.

Figure 1 is a top view of the machine,

with arrows to show the direction. of Hight.

`Figure 2 is a side elevation of the chine.

'ront propeller, as seen from above.

Figure 4 is the same' as seen in side elevation. A

Figure 5 is a front view of the yoke upon which the same is mounted, being a section taken on the line a, a, of Figure 2.

Fi re 6 is a sectional elevation taken on the line h, oit Figure 2.

Figure 7 is a sectional elevation taken on the line e, c, of Figure 2.

Figure 8 is a detail view oit the auxiliary propellers at one side of the machine, taken in side elevation, the outer bea-ring bar being omitted.

1n these figures ;-'1`he main' trame 1,oom posed of various stringers, posts, and crossbars mountedon wheels, which need no further description, supports any desired number of wings or planes 2, 3 and 4, 2 and 3 being the main wings and 4 the tail vane. These parts, also, require no further description. Projecting from the front of the frame are brackets 5,' in which is pivoted a yoke 6, by pivots at 7. 'llhe yoke 6 has within it a smaller yoke 8, pivoted therein b pivots 9, at right angles to the pivots 7. he two yokes, 6 and 8, thus constitute an eh'ective universal joint for the main propeller shaft 10, which is mounted in bearings in the yoke 8, and carries on its forward end the main The propeller arbor 10, is

in Figure 5, or equivalent dexible operative Figure 3 is a detail view of the main or connection, from the main shaft 14, and the engine 15. Connected to the yoke 8 is a handle 16, 'extending back toward the operators seat, whichfmay be placed upon the platform 17. By means of this handle the propeller may be turned up or down or laterally as 4particularly illustrated in Figures 3 and 4, so as to guide the machine 1n any one or' those directions, and this movement is permitted by the yokes and the flexible driving means, consisting in the illustration of the belt 12 and pulleys 13. Suitable catches, indicated at 18, see Figures 3,

4 and 6, serve to lock the handle, and thereb the propeller 11, in normal position. Glinde rollers'or other means not shown may be secured to the yoke 8 or at any other suitable place to keep the belt 12 always in proper engagement with the pulleys 13.

At each side of the main frame are yokes 19, pivoted inwardly to the frame 1 and out-` wardly to outboard `"bearing bars 20. ln each of those yokes 19 is mounted an arbor 21, carrying one or more auxiliary propellers 22, which may, by this means of support, be directed up or down as shown in Figure 8. thereby assisting in the propulsion of the machine in those directions. The arbors 21 are driven by means of pulleys 23 mounted, one upon each arbor in the opening of its respective yoke. These pulleys are connected by belts 24 with pulleys 25 on the main shaft 14. The arbors 21 are controlled by the operator by means of control bars 26 connected to arms 27 on the cross-shafts or pivots 28 of the 'yoke 19. These control eol bars 26 Crock the cross-shafts 28 and thereby direct the auxiliary arbors 21 up `or down as desired. The front cross-shaft maybe divided, as shown in Figure 6, to permit the movement of handle 16. The rear-cross shaft may be continuous as shown in Figure 7 or divided, as preferred.

At the top of the machine, near the front is a steering vane 29, controlled by a handle 30, which may be locked by means of notches 31 and a latch 32 shown in Figure 1, engaging` the same, and a spring 33 shown in Figure 2 to determine the engagement.

When desirable the main shaft 14 may be disconnected from the engine 15 and started, or rotated, by hand, by means of the handcrank 34, and the belt and pulley connection 35. A

Having thus described my invention, and an embodiment et' it, in the full, clear and lll@ exact terms required by law, and knowing that it comprises novel, useful and valuable improvements in the art to which it pertains, I here state that I do not Wish to be limited to the precise construction and arrangement of the several parts, as herein set forth', as theI same may be variously modified by a skilled mechanic Without departing from the spirit of the invention.

What I claim and desire to secure by Letters Patent of the United States, is the following, to-Wit:- Y

A flying machine having, in combination, a frame, oscillating yolres pivotally mounted upon said frame, arbors extending transversely through said yokes carrying on each side thereof a series of propellers, means for driving said arbors consisting of a pulley mounted on each arbor in the opening of each yoke a main driving sha-ft mounted lo upon said frame provided With a pulley, belts connecting said pulleys together and adapted to transmit the power from said shaft to Said arbors.

In testimony, that I cla-im the foregoing l 25 have hereto set my hand in the presence of two Witnesses, this 22nd day of Feb., 1919.

LORENZO FERRARI.
